Object that obstructs Dynamic Light but not LOS?

Consider a map with dynamic lighting and LOS enabled. If you have a room with columns as below, the columns 'cast' a double shadow, which is visually awkward (see below). In particular, it's hard to tell at a glance which one is the Dynamic Lighting and which one is the LOS shadow, and as the light moves through the space, the spinning double shadows ruin the 'cool factor' of Dynamic Lighting (for me). In this situation I don't want LOS for the columns, but I do want it in general (I don't want my players to see light in unexplored rooms). Is it possible to have an object that blocks light, but does not block LOS? I suppose I could use DL + FoW to achieve what I want, but then I have to manually reveal, which I was trying to avoid. Thanks

In my suggestion here: <a href="https://app.roll20.net/forum/post/1246470/special-" rel="nofollow">https://app.roll20.net/forum/post/1246470/special-</a>... I propsed the creating of special lighting layer objects that would have the ability to do all sorts of different things with the dynamic lighting. I dont see any reason not to include ones that block line of sight but not light or vice versa. I think we should combine our different lighting requests into 1 thread with a coherent system to implement all of them. Like mine! Feel free to add your suggestion/support to my thread or come tell me why I am wrong about everything.
